Global extreme natural disasters suddenly struck, and after torrential rains ravaged, the entire city was frozen. Reborn with memories of her past life, Jiang Ning awakened a portable space and hoarded massive survival supplies in advance. She formed a core team with Huo Yishen and the Malinois Ke Le, uniting Zheng Weili, Zhang Chao, Lu Yu, and others to turn the 18th floor into a safe fortress. Facing neighbors with hidden evil intentions such as her treacherous former best friend and a greedy building manager, Jiang abandoned the saintly mindset and calmly protected herself. Amidst material scarcity, severe cold, and crises of human hearts, everyone supported each other, diligently practiced self-preservation skills, guarded a warm dwelling, and struggled to survive in the frozen desperation through perseverance and strength.
